EGG-CASE-FILLER MACHINE.

Application filed August 22, 1921.A Serial-'Nm 494396.

I To all whom t may concern.:

Be it known that we, HARVEY SEGUR and'. EDWARD H. DUDDY, both citizens of the have invented certain new and useful Imrf Y provements in an llgg-Case-Filler Machine; and we do hereby declare the following to be a full` clear, and exact description of the iiivention, such as will enable others skilled in the art to which it appertains to make anduse the same. j

Our invention relates Vto machines for manufacturing the cell-cases or transversely partitioned fillers as used in crates or boxes for separating eggs, fruit or the like. Such machines as now in common usearecon-v structed for punching the required-interlocking formations on separate webs or strips of paper or cardboard, Acutting the punched webs or strips to the needed lengths, automatically assembling the strips formed from thetwo webs so as to interlock them, and feeding theresulting assembled cell-cases to the delivery table lor the machine.

'Generally speaking, our inventionv aims to simplify and expedite the making of various important adjustments on machines of this kind and also aims to expedite the positioning and replacing of thev punches and dies as used for producinglr the interlockingformations on the strip portions which are assembled by the machine into cell-cases. In operating machines ofthis general class (of which class the cell-case machine disclosed in U. S. Patent No.. 622,403 to George W. Swift, Jr., is an' example) it is important that the distances o between the unching and shearing dies associated with each paper web or strip should be vproperly adjusted, so that the interlocking formations on the relatively transverse stri s will be in proper position .45' for; enabling t e machine 'to interlock 'the same. '.Even if the adjustments for this purpose are made'with the desiredlaccuracy 'durlng the initial construction of the machine, the elongation or shrinkage of the paper or cardboard dueto humidity and other conditionsspo'ils the adjustment even when th same grade thickness of paper is used. Thepressure of the paperfeeding polls may feiect a, further dlfference in the elongation of the paper, and.' this eii'ect may likewisevary with the grade and thickness of the paper used and with the atmosphericl conditions.

Consequently, the effective distance between the punching arrangementr for notchfing and slotting each set of strips and the 'shearing means for cutting oit the same set Tof strips requiresadjustment whenever the grades or thickness of the paper are changed, .and likewise requires 'adjustment from time to time according to the varying atmospheric conditions. With the machines as now in common yuse,=such as those of thetype disclosed in theabove mentioned patent, the 'making of lsuch adjustments for the horizontally fed strip (or the one which is upwardly notched in the-completed cell-case) requires a disconnectino' or v i partial dismantling of ythe corresponding punchv and die arrangement and also requires.

-the making of the :needed adjustment by a cut-and-try'method involving' a good deal of time and hence keeping the machine idle for a correspondingly long` period. In one'of its aspects, our invention aims to obviate this loss of time and to expedite the making ofsuch 'adjustments by providing al movable f mountingfor the punch and die, together with simple means for adjustingr the p0- sition of -this punch and die without dismantling any portion of the same. v

Another adjustment. needed for such machines because of'variations .in thev shrinkage or elongation of vthe paper is that required in connection with the strips formed from the upperwe b, or those which are' `provided with downwardly open notches for 'straddling the first named set of strips. To expedite this adjustment. our invention aims to provide -simple and eiective means for throwing the upper feed rolls into and out o'f engagement with the upper web of paper,and for maintaining anv even pressure across this web so a's'to feed the same in the desired direction; uIt also aiins to provide an adjustment for this p'urpose'which willjautomatically aline the feedv rollers with Vtheir bearings, 'so as to avoid undue friction.

A further and also important., adjustment as needed in amachine' of v this type is that required for determining the distance to which the dawnwerdly ,notched Steps are the Vsupports for ion interlocking relation to the pressed downwards in assemblingl them in upwardly notched strips. Heretofore, this has been effected partly by the action of one of the cutters lwhen sliding past the cooperating cutter, these cutters being disposed in approximately the same plane. With such an arrangement, it has been diflicult to secure just the right extent of downward pressure by the movable cutter on the strip which is to .be interlocked by the action of this cutter .with a series of other strips, as any shortage of this pressure would deter the interlocking formations on the relatively transverse strips from snapping into one another, while an excessive pressure would cause the movablecutter to 'nick or indent the strips.

movable cutter from being slid out of position by resistance to the cutting, and partly by lproviding-a simple and easily ef.- fected means for varying the extent of movement of the imovable cutter and thereby adjusting the extent to which this effects the movement of the paper strip shearedof by it.

Still another difiiculty encountered with machines of this class and one which has led to a great waste of time and labor has vbeen that of attaching and replacing the punches and dies, and particularly those associated'with the u per ,or downwardly fed paper portions. eretofore, a considerable dismantling of the adjacent portions of the machine'has been required to permit of attaching or removing any punch or die, there- Vby requiring a good 'deal of labor and keeping the machine out of commission for undesirably long periods of time. Our invention aims to obviate these difficulties by providing punch and die holders so arranged that new punches and dies can' easily and quickly' be attached to the same, or detached therefrom, without detaching any other portions of the machine, and aims to accomplish this purpose -while still insuring a firm supporting and a proper positioning of the punches and dies.

Still further and more detailed objects will appear from the following specification and from the accompanying drawings, in which- Y Fig. 1 is a central and longitudinal section through the forward portion of a mainvase? chine embodying our invention, with the extreme forward end of broken away.

ile various features of ourv invention may be employed with substantially equal vfacility on a considerable variety of machines, they are particularly suited for mathe delivery table chines of the general class shown in the cited Swift Patent No.622403 and are therefore illustrated insuch a connection in the accompanying drawings. In these drawings,

'the cell-case machine includes a frame 1 supporting a table 2 over which lower strips o'f paper 3 are fed by power driven rollers 4 towards a delivery table 5 at the forward end of the machine, each strip being twisted into a vertically edgewise position by passing between a pair of closely spaced rollers 6 before it reaches the shear 7v which cuts the strip to the desired length. The paper strips 3 also pass respectively between the die head 8 and the punch head 9 of Figs. 2,

' 3 and 4, which heads carry punchesv 10 and 11 and corresponding cooperating dies for forming the edge slots 12 and the T-s'haped perforations 13 in the paper strips 3, the resulting formations being shown in Fig. 16.

The frame 1 of the machine also indirectly supports a /runway 14 disposed at a considerablel distance above the table 2 and guiding an' upper web 15 of paper to feed rollers '16 and 17, which rollers feed this out-V ward past a horizontally movable punch head 18, and a corresponding stationary die head 19, as shown in Fig. 1, and then past the stationary cutter 20. While 'being thus fed, the web 1'5 is engaged at intervals by punches 21 secured to the punch head 18 and cooperating with corresponding dies 22 carried bythe die head 19, so as to notch thc web 15 substantially after the manner shown in Fig. 15. That is to say, this web is ward into the position shown in Fig. 5, with the not hes 23 and 12 in the two paper members. respectively straddling the companion paper members and with the free edge of they web 3 disposed at some distance above the table 5. Then the movable knife 25 is swung past the path of the web 15 and in close shearing relation to the cutting edge of the stationar cutter 20 so as to shear Qft' an end of the we 15 corresponding in length to the height of the proposed cell-case, for which purpose the movable cutter '25 lis desirably mounted on a rocking lever 26 which is pivf` j oted on a rock-shaft 27 disposed below and forwardly of the cutting edge ofthe stationary knife. This rocking lever is connected by an adjustable link 28 and a swivel fork 2gftothepun'ch head 18 which is slidably mounted on a stationa guide 3() (as shown in Fig. 1') and which 1s continuously oscillated by a rod 31 connecting an eccentric strap 32 with an eccentricv fastened to the continuously rotating drive shaft 33 of the machine.

Thus arranged, it will be seen from Fig. 5 that a movement of the rocking lever 26 towards the right in that figure will cause the movable cutter 25 to shear off the lower end of the web 15,'and that the bevel of the cutting edge on the cutter 25 will act as a cam for forcing the severed end of the web 15 downwards or into effective straddling relationto the transversely disposed ,strap 3. Moreover, the inclination o f the rock shaft 26 presents the cutter 25 at a downward inclination to the web 15, so that this cutter is int-lined in a direction tending to advance the web 15; hence the movement of the cutter cooperates with the bevel of its cutting edge in forcing the severed web end down wards. By suitably adjusting the extent of movement to which the extreme cutting edge of the knife or cutter 25 passes beyond thc plane. along which the web 15 is fed downward. we can therefore insure an adequate interlocking of the downwardly fed web wit-h the horizontally` fcdstrips 3. To accomplish this adjustment and to avoid an excessive movement which might cause the (utter 25 to. nick or indent the constituent elements of the resulting cell-case, we desirably thread the link 28 and clamp it to the swivel member 29 by nuts 63 and lock nuts 64, `it being understood that link 28 extends through an Unthreaded bore in the said swivel member. Thus arranged, it will be evident from Fig. 5 that by loosening the nuts 63 and 64 we can readily vary the eff-ective length of the link 28 so as to adjust the' distance for which the cutting edge of the cutter 25 is moved beyond the path of thel web 15 during the cutting movement of this cutter. By disposing the stationary knife 20 in a. downward inclination to the web and oblique to the movable cutter, We avoid direzt thrusts tending lto shift the stationary cutter from, its position, hence Afastening 'bolts 61 extending through slots this cutter after the manner shown in Figs. 5 and 8 sutlice for' securing this in position while also permitting it to be shifted to allow for wear on its edge. However, the resistance to the cuttin will tend to slide the similarly bolted movable cutter 25 backwards (or to the left in Fig. 5) hence we desirably provide push screws 62 engaging the back of this cutter for resisting this thrust.

To facilitate the attaching, removing and replacing of the punches and dies, we do not bolt these direct to the punch heads o'r die heads after the manner heretofore customary, but first attach holders equipped for the convenient or speedy attachingor removal of the Ipunch and die parts. Thus Fig. 5 shows the punch head 18 as having a punch holder 65 secured to the same by cap screws 66. This Vholder 65 is undercut alon the face directed towards the punch hea 19 to afford a mortise formation for receiving the dovetailed rear end 34 of the punch 21, and the'holder 65 has threaded into it set screws 35 for engaging the corresponding upper bevel face of the same dovetail base, which srews desirably extend substantially parallel to the back of the panel. lBy loosening` the set screws 35, the punch 21 (including this dovetail base 34) can readily be removed and a substitute punch can easily be fastened in position by correspondingly-slipping it into place and tightening the set screws 35. The die head l19 is provided vwith a correspondingly mortised holder 36 carrying similarly dlsposed set screws 37 for the same general purpose` so thatthe dies 22 can likewise be attached or detached very quickly and without dismantling or detachi-ng any portion of the machine.

A similarly constructed punch holder 38 is desirably also mounted on the drop unch head 9 as shown in Fig. 1 for detac ably holding the punches which cut the notches and T-shaped perforations in the hori- `zontally fed strips 3.' To adjust these drop punches'lO--ll andthe corresponding dies in proper position with respect to the vertical plane-in whichthe web 15 is fed downwardly, we support both the drop punch end 9 and the drop die head 8 on a carrier 40 which slides upon guide ribs 41 on the frame of the machine, as shown in Figs. 3-and 4, and which `can be 'clamped in adjusted position by means of bolts 42. Then we connect the frame 1 with the slidable carrier 40 by a bolt 43 fastened to thepsaid frame and extending throughl an ear 44 on the carrier,

yso that the carrier may be moved backwards orforwards by adjusting nuts 45 threaded upon the bolt 43 at opposite sides of the ear 44 as shown in Figs. 1 and-4. `By manipulating the nuts 45 we can readily shift the entire carrier backward or forward of the machine, so as to adjust' the distance of the drop punch head from the plane in which the web 1-5 isfed downwardly and'from the shear 7 which isv arranged in the usual manner for shearing the strip 3 to the proper length. In practice, the amount of adjustment needed for this purpose owing to variations in the grade of paper, orV stretch or elongation of the same due to atmospheric conditlons, or on account of varying elongat ing of the paper by the pressure of the feed rolls 4 is not so much as to interfere with our using the carrier 40 also as one of the supportsffor the runway 14, so that we desirably equip a support 46 on the top of the carrier 40 as shown in Fig, 'Lfor supporting one end of the runway.

Owing to the relatively large width of the maar? feeding rolls 16 and 17, as a variation in the lfeeding pressure between the two ends of the rolls would shift the downwardly fed free end of the web sideways of the machine and hence would brin the slots 23 out of alinement with the we s 3 which these slots are to straddle. To secure thiseven distribution of. the pressure without undue friction on the bearings and to permit a ready separation of the rolls 16 and 17 when the feeding is to be interrupted, we desirably mount the bearings for one of these rolls in stationary position and provide simple means for simultaneously moving the bearings for the companion roll towards or away from the aforesaid bearings, and for latching them in any desired sition. For this purpose, Figs. 9 to 11 inclusive show the bearings 47 and 48 'associated respectively with the said two rolls as both seated in a slideway on a side portion of the frame 67 of the machine, the 'forward bearing 47 being locked in position by engaging a wall 49 in front of thi bearing and by a pin 50 inserted behind thi fbearing. The companion bearing 48 for the rear roll is left free to slide between the said side frame portion 67 and a cap 5l bolted to the latter and may be connected by a link 52 to an eccentric 53 on an eccentric shaft 54 extending-transversely of the machine and adapted to be rocked by a handled lever 55,

.it being understood that the arrangement is the same at both sides of the machine and that the single lever 55 will serve for simultaneously ,moving the bearings supporting both ends of the rolls 17. The eccentric shaft 54 is pivoted in a bearing block 56 which is also slidably mounted as shown in Fig. IO-and is adjusted in position by a set screw 57 locked by a nut 58. By loosening the lock nut 58, we can vary the distance between the eccentric shaft and the axis of the stationary roller 16, thereby correspondingly varying the closeness of approach of the two rollers to each other when the lever 55 is in the normal position in which the rolls engage the paper web Abetween them. However, by throwing the eccentric to its diametrically opposite position, we can separate the rollers to such an extent that they will not grip the web, so that the feeding will be interrupted until the lever 55 is returned to its former position. The arrangement thus disclosed therefore affords a 4simple adjustment of the rollers to match or out of feeding relation to thelweb without I stolpping the machine. owever, while we have illustrated and described both oir upper feed roller adjustment and other" tures of our maohme in highly desirable embodiments, lwe do not wish to be limited'to these,`as it will be obvious that the details of construction and arrangement may be varied in many respects without departing fromthe spirit of our invention or from the appended claims. For example, Figs. 12 to 14 inclusive lshow another form of feed roller adjustment also accomplishing the same purposes, namely one employing a compression spring 59 between the bearings 47 and 48 for continuously tending to separate these bearings and employing a thrust bar 6() interposed directly between movable bearin 48 and the eccentric 53 on the eccentric shaft 54 for resisting the thrust of the spring 59. With this arrangement it will readily be seen from Fig. 13 that by adjusting the normally locked screw 57, we can readily? va lthe position of the bar block 56 in which t e eccentric shaft is journaled, thereby causing the thrust bar 60 to lcooperate with the spring 59 `in maintaining the desired spaced relation between the bearings for the two feed rolls. With either of these Veccentricoperated roll spacing arrangements we desirably dispose each thrust member (namely the link 52 or the thrust bar 6() so that it engages the adjacent movable bearing medially of the latter, thereby permitting this bearing to rock about the thrust member vin automatically alining itselrl with the roll journaled upon it).

So also, we do not wish to be limited to the inclusion of all of the above described features in connection with each other, it being evident that they might be employed singly or in other combinations if desired, `and it also being evident thaty the application of the various features of ourv invention is by no means limited to the particular type of machine pictured and described by us.
